Key Takeaway
Consider remimazolam as a safer alternative to midazolam and propofol for gastrointestinal endoscopy due to lower complication rates.

This meta-analysis evaluated the safety and efficacy of remimazolam compared to midazolam and propofol in patients undergoing gastrointestinal endoscopies. The analysis included data from 2,455 patients across multiple trials to determine the risk of common procedural complications.

The synthesis indicates that remimazolam is associated with significantly lower risks of several adverse events. Specifically, hypotension (RR = 0.59; 95% CI: 0.43-0.81) and bradycardia (RR = 0.42; 95% CI: 0.25-0.71) were significantly lower than with midazolam or propofol. Furthermore, remimazolam showed notably reduced rates of apnea (RR = 0.51; 95% CI: 0.30-0.88), oxygen desaturation (RR = 0.20; 95% CI: 0.08-0.52), and respiratory compromise (RR = 0.45; 95% CI: 0.23-0.87). Injection-related pain was also significantly reduced (RR = 0.20; 95% CI: 0.06-0.66).

While the data suggest remimazolam may offer a favorable safety profile and serve as an effective alternative to conventional sedatives for gastrointestinal endoscopy, specific limitations were not reported in the source. Clinical application should consider these pooled results as evidence of improved safety profiles compared to standard agents.

How this fits prior evidence

This meta-analysis extends prior findings regarding remimazolam's clinical utility. It builds upon previous reports where remimazolam was shown to reduce adverse events and delirium in ventilated ICU patients, and where it was evaluated against non-remimazolam anesthesia for general anesthesia risks. This current finding specifically addresses the safety profile during gastrointestinal endoscopies, providing a lower risk of hypotension (RR = 0.59), bradycardia (RR = 0.42), and respiratory issues compared to midazolam and propofol.

When undergoing a gastrointestinal endoscopy, staying calm and stable is vital for patient safety. Doctors often use sedatives like midazolam or propofol to keep patients comfortable. However, these common medications can sometimes cause complications like low blood pressure or breathing issues.

A large review of data from 2,455 patients found that remimazolam may offer a safer alternative. Compared to the standard drugs, patients receiving remimazolam had significantly lower risks of low blood pressure and slow heart rates. The study also noted much lower rates of breathing pauses and oxygen drops during the procedure.

Additionally, patients received less pain from the initial injection when given remimazolam. While this data suggests a more favorable safety profile for this sedative, it is important to remember that these results come from a pooled analysis of several trials. Talk to your doctor about which sedation method is best for your specific needs.

Remimazolam may reduce risks like low blood pressure and breathing issues during gastrointestinal endoscopies.

Common questions

Is remimazolam safer than other sedatives during endoscopy?

The study of 2,455 patients suggests remimazolam has a favorable safety profile. It showed significantly lower risks of low blood pressure and slow heart rates compared to midazolam and propofol. It also resulted in notably lower rates of breathing pauses and oxygen desaturation during the procedure.

Does remimazolam reduce pain during the injection?

Yes, the data shows that patients receiving remimazolam experienced significantly reduced injection-related pain compared to those who received midazolam or propofol. This suggests it may be a more comfortable option for some patients during the start of their procedure.

What specific breathing risks were lower with remimazolam?

Patients using remimazolam had notably lower rates of apnea (breathing pauses), oxygen desaturation, and general respiratory compromise. These findings suggest it may help keep patients more stable while they are under sedation for their gastrointestinal endoscopy.

Gastrointestinal endoscopy serves as a key tool for diagnosing and treating digestive disorders. Adequate sedation is indispensable in achieving ideal surgical outcomes and promoting patient comfort. Recently, remimazolam has been utilized more frequently because of its good safety features, brief action time and rapid onset. This study aims to systematically review and meta-analyze remimazolam’s effectiveness and safety profile in sedating patients undergoing gastrointestinal endoscopies. We conducted literature searches in Embase, PubMed, and the Cochrane Library databases, covering the period from the establishment of each database to January 31, 2026 for all relevant CCTs and RCTs that discussed remimazolam sedation for gastrointestinal endoscopy. RevMan software (version 5.4) was employed for all statistical analyses. Eight trials involving 2,455 patients were included. In cardiovascular outcomes, remimazolam was linked to a significantly lower hypotension (RR = 0.59; 95% CI: 0.43–0.81) and bradycardia (RR = 0.42; 95% CI: 0.25–0.71) risks compared with midazolam and propofol. For respiratory adverse events, remimazolam demonstrated notably reduced rates of apnea (RR = 0.51; 95% CI: 0.30–0.88), oxygen desaturation (RR = 0.20; 95% CI: 0.08–0.52) and diminished respiratory compromise (RR = 0.45; 95% CI: 0.23–0.87). Regarding patient comfort, remimazolam significantly reduced injection-related pain (RR = 0.20; 95% CI: 0.06–0.66). Remimazolam may confer a favorable safety profile for procedural sedation in adults receiving gastrointestinal endoscopies. It could serve as a reliable and effective alternative to conventional sedatives.
